2. MUDSLIDE
 Definition: Is the movement of large amount of water
cause the rapid erosion of soil on
the steep slope. Is fast-moving landslide usually in a
channel or canal. It is also known as mudflow, when its
occur, its may cover a very small area from uphill to
downhill or its may travel over several miles from the
source

depending on its volume and speed, its
can wipe out any thing in its
path such as houses, cars, trees, as
well as electricity poles as you will
going to watch in the video from
the last slide that I will going to show.

4. CAUSES OF MUDSLIDE
 Mudslides often occur in areas with steep slopes or at
bottom of slopes or canyons. Mudslides develop when
water rapidly accumulates in the ground and result in
a surge of water-saturated, rock, earth and debris.
Mudslide usually start in steep slopes and can
activated by natural disaster.

 Rapid snowmelt at the top of a mountain or period of
intense rainfall can trigger a mudslide, as the great
volume of water mixes with soil and causes it to liquefy
and move it downhill.
Prevention and mitigation:
Before mudslide: Be aware of your environment and
be alerted always if you are in hill area.

 During mudslide: mudslides happen very fast and
there may be very little time to act. Move away quickly
from the path of the mudflow to another location. Do
not try to stay close and take photographs. Mudslide
move from uphill to downhill, therefore, avoid low-
lying areas or valleys. If there is a way to sound an
alarm, do so.

7. continuation
 After mudslide: Stay away from the location until the
emergency workers and the experts confirm that it is
safe to go back. Look out for loose wires, broken utility
lines, and hanging objects, as they may be hazards.
Report them to your rescue officials. Get in touch with
emergency officials or listen to the radio or TV on what
to do.
